Test Results

The motherboard doesn't make a big difference to performance. We've seen this before, although overclocking on this board provides a nice 12 to 16 percent boost over its stock performance.

The differences are not significant, although overclocking moves today's board from last to first, with a 6 percent improvement.

As before, it would take a very tight scale to make the differences between boards at stock look like anything. When this board is overclocked, however, there are some substantial and unexpected changes. Although the SATA performance improves by 9 percent, which is nice, the USB3.0 performance tanks, losing a whopping 40 percent. This did not make sense, but was repeatable. On my open case, nothing should be overheating (I didn't see over 39.2 degrees Celsius -- 102.5 degrees Fahrenheit -- on the VRMs at their hottest, and the CPU OC temp, coming up soon, is not unreasonable). Oddly, the last board showed the opposite effect, but to an insignificant degree. I'd love to read some suggestions in the Comments as to why this drop-off might appear.

Today’s board is dead last at stock on both the DX9 basic and DX11 custom settings, but overclocking moves the DX9 results into first, while the DX11 still trails. The differences are still only 1 to 2 percent.

Power consumption is higher than the H81 boards tested previously, but lower than the other B85 board, until overclocking. That adds another 8W-19W, depending on the application, but does not appear inordinate, nor are the temperatures coming up next.

CPU temperature mirrors the power usage results; higher than H81 boards, and lower than another B85. I think 77 C (170.6 F) is a bit high for routine use, but a better cooler should fix that.

Once again, this test is of limited value due to my lack of control over the variables. However, there are no surprises here, which I'll take as a good thing. I ran this test repeatedly at different times and after doing different tests, and these numbers are from a typical set.  There was little variance between sets.

    Why no info on the fan control for case fans? Do the 3- pin headers allow voltage control, and if so, how does the BIOS handle fan curves?

    Is the BIOS updated enough to run chips like i5 4460?

    you're joking, right? Practically every motherboard that left the factory in Q1/Q2 2014, has the support for "haswell refresh" cpus.

    This is a good question. Although there are no case fans on my testbed case, there ought to be a way I can check for this in the future. I'll keep this in mind; thanks.

    I think this is the motherboard that I said Biostar should have submitted for the sub-$60 LGA-1150 motherboard round-up, back in April.

    Better late than never, I suppose!

    Since I was asked to look at the $60-$80 segment, I suspect this board was in that range when THG ordered it; the price may have come down some. It is a nice board, it would not have been unreasonable to make it "Recommended" rather than merely "Approved," although I suspect that one of the ASRock H97 boards may be close enough in price to make that a higher bang/buck proposition.

    I remember back in 2011, with the Llano chips, if you overclocked them, the USB 3.0 controller would switch to USB 2.0 mode.

    I wouldn't have minded having it come across my bench back then. But I think Joe is right, it was probably just above the price range back then. This would have been tough competition for those other four boards, especially with the four RAM slots. That's something you get with a full-width board. That and a secured board edge ( I really don't like boards that are narrower than the spec and just hang off the edge ). Then again, the H81 chipset can't handle more than two DIMMs, even if you have the space. That's yet another advantage B85 has.

    The lack of a TOSLINK doesn't bother me. The board does have the header if you want to buy the break out adapter. But if you don't have Dolby Digital Live or DTS-Connect, you can only get 5.1 audio over the S/PDIF from pre-encoded sources, like a movie DVD. Game sounds and every other generated audio is reduced to 2.0, which you can get from the 3.5mm jack. So unless you're using your computer to watch a lot of movies, and you're using fiber optic cables for audio instead of HDMI, there's not a lot of need for it.

    I wanted a definite statement. There are boards in distant parts of the world that lack this feature.


    Firstly, apologies for not making my intention clearer. I knew exactly what I meant but, as a teacher, I should have been less hasty.

    I advise a lot of people around the world on system builds as so many of us do. What often comes up for budget systems is the PCPartpicker note. – Some Intel B85 chipset motherboards may need a BIOS update prior to using Haswell Refresh CPUs.
    Many of these posters are spending all the money they have on their first build and are full of FUD (Fear, Uncertainty, and Doubt) Often, nothing I can say will persuade them that they do not need a Z97 board like their mate told them to get.

    My statement was intended to prompt the reviewer to add wording to the review similar to what SuperVeloce suggested. Say This motherboard supports haswell refresh cpus.
    We regulars use this site a lot and 'know' all this stuff, but it is also important to remember the first-timers.

    He is right, DonkeyOatie i mean, i also built a system for a friend and i was stressed up until the system booted if i would have to run around to use another cpu to bios update so that the haswell refresh cpu i had would work.
